With this advanced digital processing we have obtained following advantages: With this advanced digital processing we have obtained following advantages:With this advanced digital processing we have obtained following advantages: With this advanced digital processing we have obtained following advantages: 1. Significantly improved dynamic range for a 16bit CD signal. 1. Significantly improved dynamic range for a 16bit CD signal.1. Significantly improved dynamic range for a 16bit CD signal. 1. Significantly improved dynamic range for a 16bit CD signal. What really matters to obtain the best musical performance is not the full level distortion (0dB), but the low level distortion: Even the poorest D/A converters has 0.004-0.005% distortion at 0dB, but at normal music levels -30 dB to -60dB, the distortion raises to several percent. The low level distortion is called dynamic range, and is normally measured at -60dB. The theoretical maximum dynamic range for a 16bit signal is 96dB. The best D/A converters can achieve a performance of about 95dB. With the intelligent high frequency interpolation a significant 5dB improvement to totally 100dB of dynamic range is obtained. 2. Effective suppression of clock jitter. 2. Effective suppression of clock jitter.2. Effective suppression of clock jitter. 2. Effective suppression of clock jitter. Jitter is due to variations in the clock rate from e.g. pulse dispersion, and will generate sideloopes to the original tone in the D/A conversion process. These sideloopes diminishes the clearness and brightness in the sound stage. Due to the asynchronous rate conversion, the input and output rate is completely independent, thus the jitter in the original signal is completely suppressed. The 192kHz output rate feed to the D/A converters is generated locally from a high precision crystal oscillator. 3. Out of band noise attenuation. 3. Out of band noise attenuation.3. Out of band noise attenuation. 3. Out of band noise attenuation. Normally the D/A converter will generate several mV of high frequency noise just above the audio frequencies (20kHz) from the delta-sigma process. This noise must be removed by analog filtering or it can disturb the stability of the audio-amplifier. However, this analog filtering means other disadvantages as phase shift in the audio band. With the 192kHz sample rate conversion, the delta sigma noise is moved up over 192kHz and only a very moderate analog filter is necessary. 4. D/A Converters. 4. D/A Converters.4. D/A Converters. 4. D/A Converters. The Burr-Brown D/A converters PCM1738 are a new revolutionary type called Advanced Segment DAC@, which combine the dynamic sound from a multi bit D/A converter and low level precision from a Delta-sigma DAC: The most significant 6 bit are converted in multi bit DAC and the 18 least significant bit are converted in a Delta Sigma DAC. With the new DIGIT II upgrade board we are convinced that the sound from your CDs will be much closer to the quality of a DVD-audio and SACD disc. In fact, we are sure that the quality of the recording on your CDs in most cases will be the bottle neck for better quality.
